The given function is:

$f(x) = -10x - 6$

To evaluate $f(7)$, substitute $x = 7$ into the function:

$f(7) = -10(7) - 6$

$= -70 - 6$

$= -76$

Thus, the final answer in function notation is:

$f(7) = -76$

Would you like a step-by-step explanation of the substitution?

2. How do you determine the slope of a linear function?
3. How do you interpret the y-intercept in a function?
4. How would you find $f(-3)$ using the same function?
5. What happens when the coefficient of $x$ is positive instead of negative?

Tip: Always substitute values carefully and follow the order of operations (PEMDAS) to avoid calculation mistakes.
